When Wolf Run came out on the IGT video platform, it was totally different from the older S2000 platform.
They got rid of the stepper reels and installed an open-framed LCD screen monitor.
Totally different MPU circuit boards, software, and cabinet.
Looks like a video game now.
Problem #1 is that the LCD monitors only last so long before they start looking old and faded.
Lot more heat inside the cabinets and stronger ventilation fans.
as far as "Rockets and Cows"...

Is she thinking of a video game called "Money Storm"?
It has cows and tornados? lol
